Specification of Letters Patent.

or BUCHANAN, MICHIGAN, Assrenons, BY MENT COMPANY, or BUCHANAN, MICHIGAN,

Patented May 1a, 1918.

Application filed January 2, 1915. Serial No. 201.

To all whom it may concern:

Be it known that we, ROBERT J. BUR- ROWS and EDWIN B. Ross, citizens of the United States, and residents of Buchanan, in thecounty of Berrien and State of- Michigan, have invented certain new and useful Improvements in Wheels, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to metal wheels designed espe'ciall for heavy use, such as on automobile truc s, and it has particularly to do with wheels of the general type shown and described in our application for patent filed of even date herewith, Serial No. 200. The invention which constitutes the subjectmatter of the present application is, a modification of the structure shown in our said application with regard to the manner in which the brake-drum and certain other parts are united therewith,the object of our present invention being to provide a construction suitable for special situations in which it is desirable to make the brakedrum separate from the wheel proper, as, for instance, where a pressed steel drum is employed in connection with a cast wheel. We accomplish this object as illustrated in the drawings and as hereinafter described.

That which we believe to be new is set forth in the claims.

In the accompanying drawings, Figure 1 -is a side elevation of our improved wheel; and

Fig. 2 is a central vertical cross-section thereof. Referring to the drawings,

Our improved wheel comprises a box-like rim 3 composed of a substantially flat tread 4 adapted to receive a suitable tire and provided with substantially radial flanges 5 and oppositely-curved members 6 extending from the inner margins of said flan es to a web 7, which connects integrally with a hub 8 by oppositely-curved members 9. Thus far, the construction of our improved wheel is substantially like that shown in our said application. As best shown in Fig.,

2, the web is provided, preferably about midway of its len h, with a circular enlargement 10, forming a seat or support the outer portion of which is turned down to form a shoulder 11 and a flange-12. The

several parts of the wheel thus far described,

including the enlargement 10, are all cast integral. 13 indicates the brake-drum, which is preferably made of pressed steel and is provided at its inner margin with an inturned flange 14 adapted to bear u on the shoulder 11 and against the outer of the flange 12, as shown in Fig. 2.

shoulder 11 and the flange 12 thus together form an angular recess into which the inner'margin of the brake-drum fits and is seated. of such diameter as to fit within the brakedrum 13 and is so shaped as to fit closely against the flange 14, against which it bears. To this end, the inner margin of the gear ring is provided with a flange 15*. dicates a. flat ring fitted between the inner margin of the flange 14, to strengthen and further support the gear ring. 17 indicates bolts which pass through the gear ring, the flange 14, and the of the web 7 for securing the gear ring, the brake-drum and the web firmly together.

By this construction it will be apparent that while the brake-drum and gear ring ace The"

15 indicates a gear ring, which is enlargement 10 are firmly secured to the wheel, they may be readily removed and replaced when necesl wing to the fact that the web 7 is sustained throughout by the truss-like rimstructure, which itself is capable of sustaining the entire load, and as the web forms a continuous connection between the rim and the hub and is elastically connected with the hub and with the rim-structure,

the web maybe made comparatively light,

The manner of securing the brake-drum to the web adds considerably to its strength, without, however, increasing its weight to an objectionable extent.

That which we claim as our invention,

and desire to secure by Letters Patent, is,

1. The combination with a wheel comprising a hub, a rim and a web connecting. said hub and rim together, said web having an intermediate support, of a brake-drum havinga flange at its inner margin adapted to bear against said support, a' gear-ring adapted to fit within said brake-drum and bear against said flange, and means for ses curin said gear ring and said brake-drum to sai web.
